Mar 26 2020 · Drug-Drug Interactions . The effectiveness of a drug can often be reduced if the action of one drug diminishes the action of another. Since drugs are commonly classified by their mode and mechanism of action any interaction affecting one drug will usually affect drugs of the same class either by interfering with their absorption or the way in which the body metabolizes the drug.
